Modelling and simulation of complex 3D woven components

3D纺织品预制件越来越多地用于航空航天工业，以提供增强的性能并缩短复合材料部件的制造时间。通过精心的设计，可以制造出网状的预成形件，从而使风扇叶片等部件能够被组装在一起。这些网状部件通常具有复杂的几何形状，在3D编织部件中，将需要使用不同的编织图案或逐渐缩放以适应的一种图案。这些模式不一定以直接的方式伸缩，并且压缩期间的行为将随着设计的伸缩而改变。无法将这些尺寸变化的影响纳入设计过程是劳斯莱斯等制造商已经确定的主要限制。该项目将开发新颖的方法，将这些复杂的部件建模到内部几何纺织品建模软件TexGen （http://texgen.sourceforge.net）中。

3D textile preforms are being used increasingly in the aerospace industry to provide enhanced properties and improve manufacturing time for composite components. With careful design, net-shaped preforms can be made which allow components such as fan blades to be constructed in one piece. These net-shaped components often have complex geometries which, in a 3D woven part, will necessitate the use of either varying weave patterns or one pattern which is gradually scaled to suit. These patterns do not necessarily scale in a straightforward manner and behaviour during compaction will change as the design is scaled. The inability to incorporate the effects of these changes in dimension into the design process is a major limitation which has been identified by manufacturers such as Rolls-Royce. This project will develop novel methods for modelling these complex components building functionality into the in-house geometric textile modelling software, TexGen (http://texgen.sourceforge.net).
